AMD FX 8320 OC Problems

[Zakkoncrakk]

So I built a new rig to mess with and have as a side computer for my 3D modeling and other projects, but I put in some pretty decent gaming PC components.
It runs fine and it gets good scores and 70+ fps in Unigine Benchmarks and can run every game at Ultra Settings 60+ fps. The main problem is my processor.
I have an AMD FX 8320. For those who don't know, it's a 3.5ghz 8-core processor with an 8-mb cache. Not really the best processor by today's standards or to you Intel fanboys (which I'll have you know I have a 6700K in my main rig), but it gets the job done. When I overclock it though, it makes my games actually run slower. Stuttering can be anything from micro-stutters to full blown freezes then a BSOD.
I've managed to OC it to 5.2ghz before just to screw around and kept it stable and cool, but I've usually kept it a 4.6-4.8ghz and this seems to slow down the performance of my PC. My BIOS settings have been adjusted to how I see fit (which may not be fit at all since it's unstable at 4.5ghz). Voltage at 1.36 no LLC adjustments, no overvoltage, no DRAM calibration, no nothing besides turning off the AMD Turbo bs and setting the multiplier to 4500mhz.
I'm not sure if this processor just can't handle being OCd that much, or I'm configuring something wrong. And, I know it's not thermal throttling, I have liquid cooling set up right now, and it never goes above 40 degrees and I have an additional 7 fans in my PC.

Specs so you can judge me:

CPU: AMD FX 8320
CPU Cooling: Corsair H100i v2
Mobo: Asus M5A78L-M/USB3 (scrapped from and older build, was not my first choice)
RAM: 16GB Corsair Vengeance 2x8GB
GPU: EVGA GTX 970 FTW
PSU: Thermaltake TR2 600W (again, not my first choice)
Fans: 7 Corsair fans in the case plus the two on the cooling radiator.

4.5ghgz needs a hell of a lot more than 1.36v try 1.44v, 4.4ghz stable at 1.35-1.38v should be doable but the extra 100mhz comes at a larger v cost.

All cpus aren't the same and your mobo ain't that good so it's anyones guess.

Unless it is AMD 970/990FX Chipset; then you generally won't have stable OC on any FX-8 series CPU. The lower chipsets don't even support FX; they work in the boards (if the BIOS has updated for that) but they will not run like an FX should (due to older chipset limitations; not being designed for FX series CPUs) so they will just act like a Phenom II in terms of performance.

While its true, that motherboard may not exactly be up to the task of such a large Overclock, making sure its using the latest BIOS could be helpful with it.

Initial support for that CPU starts with BIOS 0411, though it seems there are 2 variants for that CPU, a 125w and a 95w.

The Latest BIOS is 2101 from last year, so again, if it isnt up to date that may be the first place to start.

Board such as these would be much better suited for OC'ing an FX class CPU

As with a board such as you have currently; you could probably increase CPU VCore all the way to 1.5V and it still most likely wouldn't be stable; due to both the Chipset and poor VRMs.

I think you're letting the experience of somehow getting it stable at 5.2 ghz at one point give you unrealistic expectations. It's not acting like that now and that's just reality.

i dont understand why people keep trying to oc on cheap 760g boards.. with 125w 8-cores..
no vrm cooling, and at 5.2ghz your batting 220w tdp your going to destroy the vrm portion of the board

125w is the plain 8320 and 95w is the energy saving 8320e.

Asus says it can support ^ 140w cpus but I believe that's a stretch imho.

I fully understand that 5.2 was a lucky hit. It took my buddies and I hours to cool everything right and get the right voltages and frequencies just to get it to 5 and stay stable.
I'm starting to think pusing it to 5.2ghz may have damaged the processor because 4.5 didn't seem to be a problem before that.
Also, for those who are wondering it's a Vishera BE
